You are very welcome and if you want more advice just ask. As for your PSU I would actually suggest getting a slightly larger one of about 850W if you haven't already purchased it. This will give you a little more headroom and as it degrades over the years it will still have plenty of power. The best ones to go for have a single 12v rail and makes such as Seasonic, Corsair, Gigabyte, Enermax, Thermaltake etc are the best.
